After update from 0.7 to 1.0.0 systemd service does not start anymore error is “bundled binary not working on your system"

Corresponding to my question on help.nextcloud
-> https://help.nextcloud.com/t/update-notify-push-to-1-0-0-leads-to-bundled-binary-not-working-on-your-system/215417

i can no longer start the notify_push service on ubuntu server 24.04.1 with Nextcloud Server 30.0.5.1

System: ubuntu-server 24.04.1
PHP: 8.3.11
NGinx: 1.27.0
Reverse Proxy NGinx: 1.26.2
DataBase: PostgreSQL 17.2

I upgraded nc 30.0.4 to 30.0.5.1 and also some installed apps so as client_push (notify_push)
occ app:update --all

The upgrade was successful as far as i have tested. But a reboot of the server brought down my notify_push service and i couldn't start it anymore.

Message was: "bundled binary not working on your system"

systemctl start notify_push failed, journalctl notify_push says

My service config is as follows:

 [Unit]
Description = Push daemon for Nextcloud clients
Documentation=https://github.com/nextcloud/notify_push
After=nginx.service php8.3-fpm.service postgresql.service redis.service

[Service]
Environment = PORT=7867
Environment = NEXTCLOUD_URL=https://MY.FQDN.CLOUDNAME
ExecStart = /var/www/nextcloud/apps/notify_push/bin/x86_64/notify_push /var/www/nextcloud/config/config.php
User=www-data
Type=notify
Restart=always
RestartSec=60

[Install]
WantedBy = multi-user.target

So i tried to downgrade and made following steps:

1. occ app:remove notify_push
   → notify_push 1.0.0 disabled and removed
2. download the tar.gz file of the 0.7 version from the nextcloud apps store
   unpack the file/folder to the …/nextcloud/apps dir
3. check user rights, if all (also recursive) files → especially the binary file is accessible by the webuser (e,g, www-data)
4. command …occ app:enable notify_push
   → should report that notify_push app version 0.7.0 is enabled
5. restart the service
   → systemctl restart notify_push.service
   → systemctl status notify_push.service
6. and see this!!

The service starts with 0.7 version / binary very well with same config that made 1.0.0 crash.

Start with the service configuration and the bundled binary at apps/notify_push/bin/x86_64/notify_push, then compare the startup output from notify_push 1.0.0 with the working 0.7.0 binary. Reproduce the failure using systemctl start notify_push and inspect the corresponding journalctl output. Done means identifying why 1.0.0 reports “bundled binary not working on your system” on the stated Ubuntu and Nextcloud setup.
